SIFTER-TO'P RECEPTACLE AND CLOSURE THEREFOR.

Application filed December 18, .1923. Serial No. 681,407.

To all whom it may concern." 3

Be it known that I, GLEN S. HUMPHREY,

a citizen of the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Heretofore sifter tops for talcum powder.

cans have been usually provided with a rotary or sliding perforateddisk, or with a friction cover for closing the same, which types havebeen found to possess certain difficulties and disadvantages.

It is, therefore, the main object of the present invention to provide anextremely simple and inexpensive form of closure for sifter topreceptacles which serves to e1fec tually close the sifter openingsagainst the escape of the contents oft-he receptacle and to prevent theingress of dust, foreign matter or the like to the receptacle.

As a further object the invention comprehends a closure of the characterset forth which greatly facilitates the manipulation of the same touncover the shifter openings.

With the above recited and other objects in view, the invention residesin the novel construction set forth in the following specification,particularly pointed out in the appended claims and illustrated in theaccompanying drawings, it being understood that the right is reserved toembodiments other than those actually illustrated herein to the fullextent indicated by the general meaning of the terms in which the claimsare expressed.

In the drawings Figure 1 is a side view of a sifter top receptacleequipped with a closure constructed in accordance with the invention.

Fig. 2 is a fragmentary enlarged sectional View therethrough with theclosure in its closed position.

Fig. 3 is a similar view with the closure in open position.

Fig. 4 is a fragmentary plan view of the receptacle.

Fig. 5 is a horizontal sectional view taken approximately on the line 55of Fig. 2.

Referring to the drawings by characters of reference, 10 designates areceptacle provided with a covering apron 11 at its upper end which hassecured thereto in the usual manner an inverted cup shaped neck 12, thetop wall 13 of which 153 formed with an annular series of dischargeopenings 14.11

In the present instance upper wall 13 is pro-' vided with an upwardlypressed portion 15, the purpose of which will be hereafter set forth.l/Vithin thelower end of the neck 12 a disk. 16 is frictionally fitted,said. disk having, arcuate cutaway portions 17: definlng a centralbearlng portion 18 having a bearing opening 19. The closure memberconsists, of a disk which preferably includes a metal layer 20 and afelt layer 21 which is superimposedupon the metal layer. -A stem 22extends through an opening in the disk andan opening 23 in theupraisedportion 15 of the neck top 13.

Out-stuck ears 241 are provided on'the stem 22 above the closure memberand a coiled expansion spring 25 is interposed between the under side ofthe disk and the central bearing portion 18 of the disk 16, wherebytheclosure member is normally forced in contact with the under side of thetop 13 of the neck I to close the discharge openings 14. The

upraised portion 15 provided affords a clearance space for the receptionof the ears 2%.

In order to provide means to permit of the A retention of the closuremember in a position to uncover the discharge openings 14, the stem 22is provided adjacent its upperend with a lug 26. The opening 23 iselongated to allow for the passage of the lug 26 therethrough byslightly canting the stem 22 as illustrated in dotted lines in Fig. 3.At its extreme upper end the stem is preferably provided with a knob 27to afford means for manipulating the stem to move the closure fromclosed to open position or vice versa.

In use and operation the spring 25 nornrally functions to hold the feltlayer of the disk in close contact with the under side of the top 13 ofthe neck 12. When it is desired to dispense the contents of the can orreceptacle, the stem is forced. downwardly together with the closuremember against the action of the spring 25. After the lug 26 has beenmoved through the opening 23 the same engages beneaththe upraised portion 15, as illustrated in Fig. 3, due to the inherent tendency of thespring to straighten the stem from its canted position. It

thus follows that when the can or receptacle is inverted the powder willdischarge through the openings 17 in the lower disk and thence aroundthe closure member and through the discharge openings 14. When therequisite amount has been dispensed the user again cants the stem 22 todisengage the lug 26 which is then forced upwardly through the openingto the normal position illustrated in Fig. 2, whereby the dischargeopenings are closed.

From the foregoing it will thus be seen that a comparatively simple andinexpensive but effectual closure for powder cans or other analogousreceptacles has been provided which will function to simplify theclosing and opening operation.

I claim:

1. In a sitter top receptacle, a receptacle body, a neck provided withan upper end wall having discharge openings therein, a bearing elementsecured in the lower end of the neck, said upper wall of the neck andsaid bearing element having alined central openings, a closure devicewithin the neck including a closure disk, a stem extend ng axiallythrough the closure disk and the aligned openings and provided with astop engaging the upper side of the disk, an expansion spring encirclingthe stem and d sposed between the under side of the disk and the bearingelement, for normally moving the disk into contact with the under sideof the under wall of the neck to close the upper end wall, of means forcontrolling the closing and opening thereof comprising a closure diskmounted for movement with-- in the neck, a bearing spider secured in thelower end of the neck, aligned openingsin said spider and the upper endof the neck, a stem extending through the neck, the closure disk and thespider, said stein having ears engaging the upper side of said disk, acoiled expansion spring surrounding the stern and interposed between theunder side oi" the closure disk and the spider for noriii-alle'll'ecting the seating oi. said closure (1 sk against the end wall ofthe neck to close the openings, and a radial lug adjacent the upper endof the stern adapted to be moved through the opening in the upper end ofthe neck to engage said upper end for retaining the closure disk inunseated relation.
